WALL CONSTRUCTION 0R WALL.

Application led J'une 11, 1919.

T 0 all fr0/0m t may concern Be it known that I, JOHN H. MAGEE, a citizen of the United States, residing at Carthage, in the county of Jasper and State of Missouri, have invented certain new' and useful Improvements in lVall Constructions or lValls, of which the following is a specifi-l cation.

My invention relates to a wall construction or wall, containing relatively large min eral aggregates, coated with a binder of cement, in the central or body port-ion thereof.

In the construction of the ordinary concrete walls, for buildings and the like, it is strong molds, made of wood or iron, and' employ in their place relatively thin or narrow laths, attached to uprights or studs,

which may be of the ordinary dimensionsV or consisting of two transversely spaced upright face pieces bonded together at intervals by narrow laths, and which become a i permanent `part of the wall and function to reinforce the saine. I take irregularL aggregates, sucli as stone, brick, slag or the like, which has been broken into relatively large port-ions and screened clean of all finer particles and foreign matter, and completely coat the same with a plastic or semi-liquid cement or other binder by suitable mixing. After being thoroughly coated on all sides,

the aggregates are introduced into the inner space between the laths 'and allowed to remain undisturbed a suiiicient length of time for the cement to set and form the body portion of the wall. The coarse mineral aggregates, after setting, are bonded Vmerely at their meeting edges, and a substantially porous body portion, which will always remain dry, is obtained. Heretofore, it'f has been believed that a solid wall 4is necessary to obtain the necessary strength in building operations, but I have found that the strengthof a wall built inV the above mentioned-inanner is a great deal -in excess of actual requirements and the Wall has the Specification of Letters Patent.

advantage of being substantially porous and will thus remain dry at all times. It has been found that the outer portions of the mass of coarse aggregates will tend to pro- I ject to some extent outwardly through the spaces between the laths and the entire mass is more or less porous or containing voids. lBy reason of this construction, the outer coating of the wall, which may be formed of plaster or other suitable cemeiititious material, may be readily forced into the spacesv between the laths and into the adjacent cavities or voids of the body portion of the wall, thereby insuring a secure anchoring of the outer coating' or plaster to the body portion'of the wall.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same:

Figure l is a side elevation of a wall einbodying my invention, parts being broken away for the purpose of illustration;

Fig. 2 is a vertical transverse section, taken on line 2 2 of Fig. l;

Fig. 3 is a fragmentary detail section through the wall, showing the manner of anchoring the parts together;

Fig. i is a perspective view of one of the vertical uprights;

Fig. 5 is a plan view of a slightly different form of wall; and

Fig. Gis a transverse sectional view, taken on line 6 6 of Fig. 5.

In the drawings, wherein for the purpose of illustrationis shown a preferred embodiment of my invention, attention being called first to Figs. l and 2,'the numeral 5 designates vert-ical uprights as a whole. Each upright is preferably constructed of a pair of vertical pieces or beams 6, spaced as shown, and connected by laths 7, arranged Y upon the opposite sides thereof. These laths are preferably spaced for a substantial distance,-such as for one foot while thisdistance may be suitably varied as mayv be found advantageous. The uprights are arranged in transverse pairs and may be held in the vertical position by any suitable means. Transverse spacing members 8 are arranged between the uprights and may be rights 5 are preferably horizontal outer laths 10, which are preferably formed by sawing the ordinary commercial lath longitudinally into two portions providing laths which are about fig of an inch thick and l of an inch in width, while the invention is of course in no sense restricted to these precise proportions. i

The commercial lath may be cut diagonally, providing inclined faces 11, as shown. The laths 10 are preferably arranged about one-inch apart, but this distance may be varied as found advantageous.

As more clearly shown in Figs. 2 andB, the space between the uprights 5 and the laths 10 is filled with relatively large mineral aggregates 12, and I prefer that these mineral aggregates be of a size that will ass through a screen of one-inch mesh, and lie retained on a screen of one-half inch mesh, while this precise size may be varied. The mineral aggregates may be broken stone, bricks or the like, and it is to be distinctly understood that these mineral aggregates are not finely divided, such as pulverized or crushed, vbut are relatively large irregular pieces, screened clean of dust and fine particles. Prior to `being introduced into the space between the uprights and laths these relatively large mineral aggregates have all sides thereof thoroughly coated with a semi-liquid or plastic cement, or other cementitious material or binder, by suitable mixing. i After the relatively large mineral aggregates are thus coated, they are introduced into the space between they uprights and laths and are allowed to set and harden. These mineral aggregates become the main body of the1wall which is continuous by incorporating the hollow open work uprights 5 as a part thereof, particular attention being called to the fact that these mineral aggregates pass into the `hollow uprights filling the spaces therein.

These hollow open work uprights do not interrupt the integrity of the wall. Themineral aggregates produce a wall, whichv is provided with `relatively large voids throughout its cross sectional area, it being.

distinctly understood that the cementit-ious material is simply applied tothe surface of the mineral aggregates in a proper amount to coat such surfaces, but is not present in a suflicient amount to lill the voids between the mineral aggregates. As more clearly shown in Fig. 3, the outer portions of the mineral aggregates pass or project more or less into the spaces between the laths 10, interlocking therewith and forming Va highly irregular surface. This isv an important feature. j

The aggregates forming the main body of the wall are thus arranged to produce a substantially porous structure and, at the same time, are `secured to each other at laths, thereby penetrating the voids in the outer portion of the wall for a substantial distance, whereby such coating is securely anchored to the body portion of the wall.

Particularattention is called to the fact that the vertical members and lathsbecome permanently embedded `or inclosed within the material of the wall, and they function as reinforcing means for the same while being protected and surrounded by the material of thevwall from the action of the air or weather, thereby prolonging their life. In Figs. 5 and 6, I have shown a hollow vwall construction, embodying wall sections 14. Each of these wall sections are similar to the wall shown in Figs. 1 and 2 and comprises hollow open work uprights 15 similar to the uprights 5 but Vhaving a slightly dif' `by the relatively large'mineral aggregate 18 coated with the cementitious material which passes into the hollow open work uprights 15; and the space between the transverse laths V17 is also `filled with the relatively large mineral aggregates to produce a transverse column 19. A coat 2O is applied to the outer surface of the wall sections 14.

It is to be understood that the forms of my invention herewith shown and described are to be taken as preferred examples of the same, and that various changes may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus claim:

1. In a wall construction, a skeleton described my invention, I

frame formed of two sets of laths, a filler of i relatively large mineral aggregates arranged within the 'space between the two voids throughout the wall but being bonded at the meeting edges of the aggregates, and

an outer coating of cementitious material secured to the exposed surface of the laths, and engaging the surface of the filler.

2. In a wall construction, a skeleton frame formed of vertical uprights arranged in two sets to form the front and back of the wall, and spaced laths secured to the outer sides of the uprights, a filler of relatively large mineral aggregates arranged within the space between the laths, said aggregates having their surfaces coated with a cementitious material, the filler being of such size as to produce voids throughout the wall but being bonded at the meeting edges of the aggregates, and an outer coating of cementitious material secured to the eX- posed surface of the laths, and engaging the Surface of the filler.

In testimony whereof I affix my signature in the presence of two witnesses.
